Harrison Hall is an academic building on the campus of Miami University housing the Department of Political Science and the Center for Public Management and Regional Affairs.

[5] The first day of classes at Miami University began on November 1, 1824 in Franklin Hall, which was the only classroom building on campus at that time.

The first two student organizations, the Erodelphian and the Union Literary Societies, began in 1825 and met on Friday evenings on the third floor of Old Main, debating issues involving social and economic progress, including slavery and feminism.

However, not wanting to close the university, the Board of Trustees fired MacMaster and hired William Anderson as the next president, who allowed Phi Delta Theta fraternity to be formed in December 1848.

It was spotted by a group of students on Sunday, December 1 at 7:45 p.m. resulting in 150 dollars worth of damage, and destroyed one of the stained glass windows inside of Harrison Hall.

[10] On April 29, 1957, the State Department of Industrial Relations condemned any further instructional use of Harrison Hall after a building inspection.

The Board stated that the new Harrison Hall should be devoted to classroom purposes and that it would house the departments of Sociology and Anthropology, Psychology, Government, and the Scripps Foundation.

[2] A memorandum by then President John D. Millett on April 3, 1959 discussed the potential distribution of rooms and offices within the new Harrison Hall, also stating which departments would be housed within the building.
